(一)在米丘林生物学的领域内,无性杂种的获得,是一件很大的成就,因为这工作不但向以染色体为遗传物质基础的门德尔莫尔根遗传学提出了挑战,而且在育种工作实践上也有很大的意义,但是,我认为无性杂种的问题,目下在遗传学上还是无能为力的,因为到现在为止,我们只有无性杂种事实获得的报道,而还没有获得无性杂种的规 (A) The acquisition of cloning in the field of Michurin biology is a great achievement, as it not only poses a challenge to Mendelian root genetics that uses chromosomes as a genetic material, but also In practice, breeding work is also of great significance, but I think the problem of cloning is genetically still powerless, because until now, we have only reported the cloning of asexuality, but have not yet obtained the clonal hybrid regulation
